CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Provisional Patent Application Ser. No. 62/292,342, filed Feb. 7, 2016; the contents of which are hereby incorporated by reference herein in their entirety into this disclosure.

TECHNICAL FIELD

The subject disclosure relates generally to a leveling and stabilizing device for furniture supports and the like, and more particularly to a stabilizing device for a foot member or furniture legs or supports.

BACKGROUND

Flexible vacuum cups and suction cups are well known and in use for attaching the suction cup to an object.

It is often observed that there are instances when a table or chair does not securely sit on the floor or ground in which it is located. This could be due to the fact that the floor or ground is not completely level or has slight height variations in the surface causing one or more of the legs of the table to rest uneven on the surface of the floor or ground. This unevenness oftentimes creates a gap between the bottom of the leg and the floor or ground. This gap can also be caused when the legs of the table or chair are not of equal length, despite the floor or ground being free of slight variations. Oftentimes both of these conditions exist, i.e., the table or chair legs are not of equal length and the floor or ground surface has slight height variations. This is most common when visiting a restaurant, particularly outdoor patios. It has been often observed at outdoor patio restaurants that the serving tables will rock or be unstable because the floor or ground is uneven or the table legs are not of equal length.

Currently there are a number of solutions that have been attempted to put a device under a table or chair leg that is not securely positioned on the ground or floor. Some of these solutions include using pieces of paper, napkins, sugar packets and/or utensils under the legs. Unfortunately, these attempts are not durable solution and quickly become undone when the table is moved ever so slightly with its intended use.

Another conventional solution has been to use a hard piece of material, such as wood or metal as a shim. Unfortunately, this solution is also insufficient, since again any movement in the table will cause the shim device to shift and no longer provide a secure footing for the leg of the table or chair. Hard materials do not mold or adjust to the variety of gaps that cause unstable table and chair annoyances. These gaps are continually different as tables and chairs are continually repositioned in different areas of the floor or ground.

There is a longstanding need for an innovative solution that can quickly and easily stabilize an un-level, rocking table or chair that would automatically change its form to properly fill out the gap created between the un-level table or chair leg and the ground that the table or chair stands on. Likewise, it is also desirable to have a solution that is durable and can sustain repeated movement and use under the leg of an item of furniture.

DETAILED DESCRIPTION

Particular embodiments of the present subject disclosure will now be described in greater detail with reference to the figures.

FIG. 1 illustrates a stabilizing device 10 provided on the lower end of a leg 5 of a chair that would otherwise be lob-sided. The stabilizing device 10 is adapted for use as a floor-engaging element or foot member which may be provided on a supporting portion such as a leg of furniture or the like. The stabilizing device 10 is easy to use, durable, automatically self-molding and self-leveling for non-level tables, chairs, furniture and other units having legs or the like in both private residences and commercial businesses.

In the illustrated structure, the stabilizing device 10 is presented for use on the lower end of a leg 5 of a chair. The stabilizing device 10 may be constructed relatively simple, reliable and inexpensive. The stabilizing device 10 has broad applications and may be provided for leveling and stabilizing under a table leg, chair leg, or similar related product that requires slight adjustment to create a solid connection to the floor. The stabilizing device 10 has universal application, other than furniture (e.g. table, chair, cabinet, shelf, couch) or appliance (e.g. washer, dryer, etc.), the subject disclosure may be applied to any object (e.g. table lamp, printer, etc.) that needs balance on any surface.

FIGS. 2-3 show perspective views of an exemplary stabilizing device 10. FIG. 4 shows a cross section view of the stabilizing device 10. Although a variety of different shapes may be used, the stabilizing device 10 is cylindrical in shape and includes a first face or side 20 and a second face or side 30 bounded by a concentric side wall 40.

The first side 20 has a raised ring 22 that is disposed adjacent to an outer peripheral edge 23 of the first side 20. The raised ring 22 may be constructed in a variety of different shapes and sizes. The raised ring 22 is adapted to secure a leg 5 of a piece of furniture or an item having legs used as a base.

FIGS. 3-5 show the second side 30 including a concentric recess 32 that is disposed adjacent to an outer peripheral edge 23 of the second side 30. The concentric recess 32 may be constructed in a variety of different shapes and sizes. The concentric recess 32 of a first stabilizing device 10 is adapted to snugly receive a raised ring 22.

As shown in FIG. 5, the raised ring 22 from a second stabilizing device 10 may be stacked on top of the first stabilizing device 10. It is to be understood that the stabilizing device 10 can be shaped into various sizes and shapes, such as but not limited to a circle, square, an obtuse shape or other suitable shape according to this subject disclosure.

FIG. 6 shows that the height of the concentric side wall 40 may be constructed at various predetermined heights in order to shore up or level furniture legs 5 at a desired height. One or more stabilizing devices 10 may be adjustably stacked on top of each other to obtain the desired height. Likewise, the various stabilizing devices 10 may be of different heights. For example, if the desired height to be lifted is a one inch, two stabilizing devices 10 at ½ inch may be stacked on top of each other to elevate a leg one inch. Alternatively, a ½-inch height first stabilizing device 10 and a second ¼-inch height stabilizing device 10 can be stacked on top of each other to obtain a ¾ inch height such as illustrated in FIG. 6. As such, it is to be understood that various stabilizing devices 10 of different heights can be stacked to obtain a desired height.

The stabilizing device 10 is preferably molded or otherwise suitably formed of material capable of withstanding a great deal of stress without failure. Likewise, the stabilizing device 10 is abrasion resistant, has a long life, without little to no age hardening. The stabilizing device 10 may be molded from a synthetic resin, such as for example, polyethylene, since polyethylene is a low pressure, high density material. Other materials such as rubber or flexible plastics, such as nylon, may be used. The stabilizing device 10 is made of a material that is durable, albeit flexible and soft and capable of supporting the weight of substantially heavy furniture.

The stabilizing device 10 may have different sizes, hardness/softness characteristics, shapes, colors and widths (including widths that may be tapered or irregular) to fit various uses to solve the problem of gaps between table or chair legs and the floor or ground. The stabilizing device 10 is self-adjusting to automatically fill the gap or crevice and mold to the area between a table or chair leg and the ground or floor. Furthermore, the stabilizing device 10 continuously adjusts to the movement of the leg 5 of the furniture item while the leg 5 of the table or chair is against the ground or floor to maintain a secure footing.

The materials of construction for the stabilizing device 10 may also be made of a rubber. The preferred hardness of rubber is determined by an international standard for measuring hardness, called the Durometer. Within the Durometer various scales may be used depending upon the material type. The scales are defined by the word “Shore”, followed by a letter to classify the material. Generally, a low number means that the material is soft, whereas higher numbers mean the material is hard. Various Durometers at different Shore scale may be suitable used with this subject disclosure.

Likewise, the stabilizing device 10 is substantially pliable to allow offset legs 5 to slightly sink into the stabilizing device 10 to balance an uneven leg from various other legs, which may be positioned slightly higher or longer. The material of the stabilizing device 10 is also suitable for providing a gripping action against the surface onto which it is lying on top of. A peelable release paper may also be provided on the first side 20 or second side 30 of the stabilizing device 10, under which an adhesive may be provided to assist in the gripping action.

As shown in FIGS. 2-6, the raised ring 22 may be dimensioned to be adapted to receive various different sized legs. Within the raised ring 22, a recess or socket 24 is formed that is adapted to receive the leg 5 within the socket 24. As shown in FIGS. 2-5, the socket 24 may have a 90-degree angle between the inner surface 22 a of the ring 22 and an upper surface 22 b of the ring 22 and an outer surface 22 c of the ring 22.

FIG. 4 shows a small aperture 27 may be provided in the stabilizing device 10 to allow air to escape from the socket or recess 24 when the leg 5 member of a piece of furniture is being placed on top of the stabilizing device 10 to allow any residual air trapped to escape and allow the leg 5 to seat securely on top of the stabilizing device 10. The aperture 27 may be provided through the stabilizing device 10 at any suitable location where venting may occur.

FIG. 4 also depicts a slope or rounded edge 28 at the outer periphery 23 of the second side 30 adjacent to the concentric side wall 40. The rounded edge 28 may be constructed to slope upwardly, instead of having a hard flat angle. The advantage of incorporating the rounded edge 28 around the peripheral edge 23 is to provide a slight inclined edge to facilitate movement of the stabilizer device under the legs 5 of furniture to slide up and over slight imperfections or upward projections in the floor or supporting surface.

FIG. 7 depicts an alternative construction for the stabilizing device 10. As shown, the relationship between the slanted or inner angular shape wall 22 d and the upper surface 22 b may have an angled shape. The angular shape wall 22 d will account for receipt of varying sizes of the legs 5. The slope of the angular shape wall 22 d will direct the leg 5 of the furniture item to the center of the stabilizing device 10 creating a stable footing. The concentric recess 32 on the second side 30 of the stabilizing device 10 is also constructed to include a second angular shape wall 32 d to mate with the angular shape wall 22 d of the angular shape wall 22 d of the raised ring 22.

FIG. 8 shows yet another alternative construction to having a ring adjacent to the peripheral boundary of the stabilizing device 10. As shown, the upper first side 20 of the stabilizing device 10 may have a bowl shaped or spherical concave contour 26 adapted to receive therein a leg 5 of an item of furniture. The spherical concave contour 26 extends to an edge 22 e near the peripheral edge 23 adjacent to the concentric side wall 40. A step 26 a is provided between an edge 22 e of the spherical concave contour 26 and the peripheral edge 23. The step 26 a mates with the lower edge of the second face 30 of another stabilizing device over which it may be stacked as shown in FIG. 8.

Likewise, the second side 30 can be a contoured surface 36 adapted to mate with the bowl-shaped or spherical concave contour 26 of the first side 20. In this manner, secure stacking is also possible amongst various stabilizing devices 10 as shown in FIG. 8.

While the stabilizing device 10 is shown to be substantially cylindrical, it is to be understood that the stabilizing device 10 may be of any suitable geometric shape or the like adapted to correspond to the leg 5 of a piece of furniture according to this subject disclosure.

In assembly, a leg 5 of a piece of furniture is positioned over and in axial alignment with the recess 24. The leg 5 member is then placed on top of the recess 24. The weight of the furniture item will sink into the resilient material of the stabilizing device 10 until the leg is leveled out with the other corresponding legs on the furniture item. The raised ring 22 will firmly secure the leg 5 within the stabilizing device 10.

The load from the leg and the furniture item is distributed over the recess 24. The stabilizing device 10 is not subject to corrosion, is wear-resistant, capable of withstanding great stress, and will have long life without danger of marring or damaging a floor or other supporting surface upon which it is situated.

It is to be understood that the stabilizing device 10 is not to be limited to the specific form or arrangement of parts herein described and shown except insofar as such limitations are included in the claim.
